<ConfigurationPropertyAttribute("minFreeThreads", DefaultValue := )> _
<IntegerValidatorAttribute(MinValue := )> _
Public Property MinFreeThreads As Integer

Property Value

Type: System.Int32
The minimum number of free threads in the common language runtime (CLR) thread pool before a request in this configuration scope will be serviced. The default value is 8.

The MinFreeThreads property defines the minimum number of free threads to execute a request. If a sufficient number of threads are not available, the request will remain queued and periodic checks for thread availability will continue until the required amount of threads are present. The default value is 8.


ASP.NET keeps this many threads free for requests that require additional threads to complete their processing.

The following example shows how to use the MinFreeThreads property.

' Get the MinFreeThreads property value.
Response.Write("MinFreeThreads: " & _
  configSection.MinFreeThreads & "<br>")

' Set the MinFreeThreads property value to 16
configSection.MinFreeThreads = 16
